The difference between polyester resin vacuum packaging bags and PE nylon vacuum packaging bags

Polyester vacuum packaging bags are vacuum bag materials made from PET as raw material, extruded into thick sheets, and then biaxially stretched. It is a colorless, transparent, and glossy vacuum bag with excellent mechanical properties, high rigidity, hardness, and toughness, puncture resistance, friction resistance, high and low temperature resistance, chemical resistance, oil resistance, air tightness, and good fragrance retention. It is one of the commonly used materials for barrier composite vacuum bags. However, the price of polyester vacuum bags is relatively high, usually with a thickness of 12 μ m. They are commonly used as outer materials for steaming and cooking packaging, and have good printability.

Nylon vacuum bag is a very tough vacuum bag with good transparency and good gloss. It has high tensile strength and tensile strength, as well as good heat resistance, cold resistance, oil resistance, and organic solvent resistance. It has excellent wear resistance, puncture resistance, and is relatively soft with excellent oxygen resistance. However, it has poor water vapor barrier properties, high moisture absorption and permeability, and poor heat sealing properties. It is suitable for packaging hard items such as greasy foods, meat products, fried foods, vacuum packaged foods, and steamed foods.
